EPICKEB-STRAP FOR LOOMS. A

Application filed May 22, 1909. Serial N0. 497,636.

To all whom it may concern:

Be it known that I, VAPoLnoN LEMAIRE, of Taunton, in the county of Bristol and Commonwealth of Massachusetts, have in .ventecl an Improved Picker-Strap for Looms, of which the following is n specification.

Thefebjects attained by my invention are (1') the increased facility of attaching and detaching the cushion described in my Patent #848,150, of Api'. 24,1900, (2)flesseniug the liability of said cushion being displaced by loosening of the bolt at its lower entl, eliminating all possibility ofwrinkling of said cushion, (4) increased stability of the cushion-holder. (5) increased ease and.

elasticity of operation.

My invention consists in the novel construction and arrangement of parts, as setforth in the following description, reference being bad to the drawings appended hereto, in which similar characters refer to corresponding parts in all the figures. Figure 1 is a side elevation of one form of my lmprovecl.picker-strap, and Fig. 2 is s top plan View of ithe same. Fig. 3 is on enlar ed side elevation of the cushion-holder J in ig. l and Fi 4 is an end elevation of thesame. Fig. 5'15 :1 side elevation of an other form of my invention and Fig. (5 is a top plan View of the same. Fig. 7 is an end elevationof the cushion carrier in Figs. 5 and 6.

In Fig. 1, A and A.represent two strips or Wires, (preferably steel, although Wood or other suitable substance may be used, alone or in combination,} upon one end of which is secured a. hub E, lined with e bushing of leather ml orother suitable imitcrial I l I adapted to denden impact. Through ns hub extends an axle D, which may be tustened in any convenient way to the pickershei't of a loom. The purpose of the bus, ing C is to cleaden the inipact of members B and 1) upon each other, and thus increase the elasticity and smoothness of running and decrease noise. In Figs. 5 and 6, a. similar object is attained by bolting a cylindrical block of leather, or other suitable material represented by E between the ends of strips A and A. by bolt F, block E acting as an axle for eye G .on arm H, which fastened to the picker-shaft of the loom. At the opposits ends of-stri s A and A is a cushionholder 'J preferab y mode in the form hereinofter clescribed, and may either be cast in one piece or stamped from sheet motel aid riveted together.

yateneecllllnr. 22, will,

In Fig. 3, being an e nlargediorm of J in Fig. 1, l is the body of the cushion hcleler,

haying a shoulder 2 integral therewith, jecting from the concevesiile of 1 end having its top and bottom fiat. A screw-bolt, 3 passes verticully through this shouldec, so

placed that its square head i has oneside restingin parallelism against the well of i, so that head 4 cminotrevolve. From the top of 1 project luteruliy lugs 5, notcheil unclerneaih at (5 find from the bottom oi 1 are, corresponding lugs 7 similarly notcheil M8, the space between lugs 5 curl 7 being just sufficient to allow the passage theretln'ongh of strips A and A From one of lugs 7 an arm il extenos downward, being bent at right angles at. 10 and having a horizon'izil pin 11.

Between the outer enil of pin 11 and the lug 7 nearest it is s soace suiiicient to allow the passage of a strip of leather, (see lg, l) which forms the cushion the picker-strap. By means of this constr: tion, I have increased thefec with Which the QUSlIlOII-bLKlPS can be 0.75 tacheol or (letachecl, as all the; nceii be clone now when attaching the cushion is to loos strip of leather and slide it around pin .1, and then fasten the ends of it to the picker-- stick L. In my present-invention,also, there is no bolt and nut securing cushion K to holder .1 to jar loose end thus letcushion K become disoluced. Still another envenu A r v c Q: accruing from mrnnng; on on passing it single strso nrouncl 2. pin is lessen m the liabilit o. Tilliillll the cushion. c; l .1 I h 1 v n in the course or ong service, the layer or cushion next the icker-stick 1S roilco. out so that it becomes longer than the layers benmd t, and snne, in my ioiinei mvcnnon,

both ends of the cushion were fixed by bolts or screws, the layer nearest the pickenstick would Wrinkle and buckle up, but by my improved method this uneven lengthening is rovicled for, {is the strip of leather K is free.

to'move on pin 11. The lower surface of l is out obli web as at 12, to allow cushion is.

to lie snugly against the convex surfuce of holder 5 A list clamp 13, with ends bent down to embrace the sop of strips A and A is ierc-ed by boll; 3 and is clamped onlo strips A and A by tightening nut 14:, th s raising shoulder 2 and so tilting cuslisionof A (see Fig. 7), so that plate 19 is held holder J that lugs 7 bite into the under side i and lugs 5 into the upper side of stri s A and A}. All danger of the carrier slipping laterally or rotatably on strips A and A is thus obviated The cushion K, of leather or other suitable material, is looped around pin 11, in the manner shown in Fig. 1, so that two thicknesses thereof pass upward between the convex side of holder J and picker-stick L, the ends of K being fastened to L by a screw M or similar means.

A different form of cushionholder, embodying the same advantages, is shown in Fig. 5, in which stri s A and A are slotted, as at N and a cushion-carrier P is slidably mounted therein, thus affording opportunity of adjusting the picker-stick at will. Cushion-holder P, see Fig. 7, consists of a blookof leather, wood, or other suitable material, 15, inserted between A and A through which passes a bolt 16, having on one end a nut 17 and on the other a broad head 18. Between head 18and strip A a .plate 19 issecurely clamped by tightening nut 17. Plate 19. has at its lower end a horizontal pin 20 fixed thereto, similar to and for the same purpose as pin 11 in Figs. 3 and 1. Plate 19 has a horizontal extension or lug 21 at its top, which extends over and snugly fits the upper surface of strip A, and a similar lug 22 engages the bottom fixed at the proper angle to strip A and. at the same time kept from Sliding in slots N by tightening nut 17. This form of carrier is designed to afi'ord additional cushioning where the picker-stick strikes the pickerstrap, thus insuring great ease and clasticity of operation.

states An alternative" method of regulating the length of the"picker-strap is shown in Figs. 5 and (5. Between the ends of A and A is inserted one end of a fiat plate A in which there is a longitudinal slot S having escalloped edges T, and its other end is fastened by bolt R between strips A and A", which form a continuation of the pickerstrap. Bolt W passes through holes in the ends of strips A and A and through slot S, enmeshing in the escallops 'l, and thus when nut Y is tightened, all possibility of slipping, is eliminated.

Having described my invention, NVllilll I claim as new and desire to secure by Letters Patent is,-

1. In combination, a picker strap composed of strips comprising a frame, a carrier mounted thereon, a pin having one end free attached to said carrier and lying below and transversely to said strips, a picker stick, and a strip of material looped around said pin, passing double between the carrier and the picker stick and fastened to said picker stick, as and for the purpose dcsci'ibed.

2. In a picker strap, the combination of strips comprisin a frame, a cushion holder, having a shoulder integral therewith, slid ablymounted on said frame by means of lugs, and a clamp having for members said shoulder, a plate resting upon said frame, and a bolt and nut connecting said shoulder and plate, as and for'the purpose described.
